This invention relates to an improved attachment for automobile and motor vehicle headlights.

The principal novelty is predicated upon a mechanical attachment for the casing of a bulb equipped headlight structure wherein said attachment is especially constructed and developed to modify the light beam to provide a beam having intensified illuminating properties.

In carrying the inventive conception into actual practice, l have selected a simplied ent'retaining member 19, the latter being arand systemmatic arrangement of parts calculated to fulfill the requirements of a structure of this class in a dependable, eliicient and satisfactory manner.

'Other features and advantages will become more readily apparent from the following description and dra-wings.

In the drawings, the numeral 5 in Figure 1 designates a parabolically shaped casing provided with suitable reflecting means, and provided as is usual with a centralized incandescent bulb 6. In accordance with the present invention, the casing has a marginal y retaining channel 7 to accommodate the annular mounting for the light beam rec-tify-.

ing attachment.

The attachment as seen in Figure 4l comprises a tubular` cylinder 8 provided at its front with a conical beam concentrating shell 9. This shell is of truncated conical form and the truncated apex 10 constitutes the restricted exit for the light beam. This is arranged in co-aXial alinement with the focal center of the bulb.

Thus, thecrown portion of the con- A coil spring 17l is arranged within the cylinder and pressed against the'lenses for holding them in place against the abutmentL The elements for the lens 14 in clude aretaining ring 18a and asplit resiliranged` within the inner end portion of the concentrating shell 9.

The mountings for the lenses, cylinder and shell are made up of three parts. The numeralsy 2O `and 21 designate complemental annuli and an intervening transparent annulus 22. These annularmembers 20 and`21'y are formed with registering holes 23 which co-operatefwith the transparent annulus `22 vin forming windows.

The nurmerals 30 designate slotted lugs carried by the cylinder through which the bolts pass. Thus the bolts serve to assemble the parts in the relationship disclosed in Figure 1.

I shalll not however, attempt `to disclose theoretically the exact projection of light 5 rays developed by the addition of this attachment, for these factors will be evident to students'learned in this particular line of endeavor. f v l f The main features to be observed are these..

I have found it practical to use a pairy of duplicate magnifying lenses and arranging these in reversed contact orderfin a suitable holder, preferably an open-ended cylinder of the type representedby thenumeral 8.1

These lenses must be positioned `in proper co-axial lalinement with respect yto the bulb in the main headlight casing and preferably yco-op'erate with a concentrating projecting shell. f

The specific type of mounting utilized is of course like that shown in Figure 4 but may vary as occasion requires. The principal idea is to employ a mounting susceptible of supporting the attachment 1n proper position in the headlight casing and i providing the mounting with circumferentially spaced windowlight to serve as indicators representing the actual diameter of the main headlightcasing for safety recognition purposes.

` I claim v'In combination kwith a head lamp includ-y ing a lamp bulb, a cylinder of much smaller diameter than the front end of the head lamp `andhaving both ends open,-amounting encircling the cylinder at substantially the midi, dle portion of the cylinder and having its periphery connected with the front of the head lamp'for supporting the' cylinder in the head lamp `with its inner end close to the 40 bulb, a pair of lenses in the cylinder each formed with a fiat outer face and a convex inner face,the flat faces being arranged adjacent the ends 'of the cylinder, a conical member having its large end connected `to 46 the outer end of the cylinder with its small end open for preventing glare when the rays of light are passing through thelenses, means for longitudinally adjusting the cylinder in the mounting, and said mounting having a 50 plurality of window forming openings therein, said openings being arranged iny a'sub-v stantially annular row' in the mounting, whereby7 some of therays of light from the bulb will pass'through said openings;
